Abstract

A METHOD FOR CONTINUOUS MANUFACTURE OF HIGHER-STRENGTH, LOWER-SALT, AQUEOUS SODIUM HYPOCHLORITE BLEACH FROM LOWER-STRENGTH AQUEOUS SODIUM HYPOCHLORITE BLEACH THAT HAS SOME SODIUM HYDROXIDE AND THAT IS ESSENTIALLY FREE OF SODIUM CHLORIDE (SALT) CRYSTALS, AQUEOUS SODIUM HYDROXIDE SOLUTION HAVING A CONCENTRATION BY WEIGHT WITHIN A RANGE FROM ABOUT 45% TO ABOUT 51 %, CHLORINE IN GAS AND/OR LIQUID PHASE THAT MAY OR MAY NOT INCLUDE INERTS, AND A RECYCLE SOLUTION. SLURRY IS WITHDRAWN FROM THE TANK (12) AT A LEVEL BELOW WHERE THE LOWER-STRENGTH BLEACH, THE SODIUM HYDROXIDE SOLUTION, THE CHLORINE, AND THE RECYCLE SOLUTION BEGIN TO MIX WITH SLURRY ALREADY IN THE TANK (12). A FIRST PORTION OF THE SLURRY IS WITHDRAWN AND USED AS THE RECYCLE SOLUTION. A SECOND PORTION OF THE SLURRY IS WITHDRAWN AND PROCESSED TO SEPARATE SUBSTANTIALLY ALL SALT CRYSTALS FROM RESIDUAL LIQUID THAT IS RECOVERED AS THE HIGHER-STRENGTH LOWER-SALT, AQUEOUS SODIUM HYPOCHLORITE BLEACH.
